WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 633,644, datedSeptember 26, 1899.

Application filed April 15, 1899. Serial No. 713,192. (No model.)

To (all whom, t may concern.-

Be it known that I, CHARLES HUsr FOX, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and use? ful Improvements in Water-Heaters, ofwhich the following is a specification.

Myinvention relates to water-heaters of the class intended to supplyheat or hot water to buildings, its obj ect being to provide a heateradapted to accomplish either or both these purposes with one apparatus,and also to provide a simple construction of removable andinterchangeable parts or elements, admitting repairs with but temporarycessation of operation.

Apparatus embodying my invention is illustrated in the accompanyingdrawings, in which- Figure l is a side elevation, partly in section, ofmy improved heater; and Fig. 2 is a top plan View of same with thesmoke-dome removed.

Referring now to the drawings, A designates a water-jacketed shell ofplain cylindrical construction constructed in the usual manner of outerand inner shells a a2, riveted to upper and lower rings b b2, providedwith a grate c and smoke-dome c2 and the usual nre and ash-pit doors CZd2, which may be furnished with a heat-regulatin g device B of anyapproved description. These parts do not differ materially from ordinaryconstructions and will be readily understood without a more detaileddescription.

Arranged concentrically within the jacket A, above the fire-grate, are aseries of vertical manifolds E, consisting of upper and lower headers ee2, united by parallel tubes t. I prefer to form the headers ascentrally open segments or triangular structures, as indicated, andarrange the connecting-tubes in divergent lines extending at the sidesand back of the headers from a single tube at the apex, thus giving toeach manifold independently a considerable heating-surface. Vhere theapparatus is to be used for a single purpose, all the manifolds E areconnected to the water-space of the jacket A by branch pipes e5 es,tapped into the upper and lower headers e e2, respectively, and thenceinto the inner shell a2. These connections are so made as to be easilydetachable, so that when necessary to remove a manifold for repairs theapertures of the shell a2 can be temporarily plugged and the apparatusstill used without the absent manifold. In case it is desirable to useone or more of the manifolds for an independent purpose-for example, asa special water-heate'r for a bath-sleeves X are inserted through theouter and inner shells a a2 of the jacket A for the upper and lowerconnections of a given manifold or set of manifolds E, and theconnections e5 e6 are carried outward through said sleeves and thence toa suitable tank provided with the usual connections with the water-main.When in use, I prefer to place a plate p centrally on the top of themanifolds, as indicated in Fig. 3,

to compel the heated air and gaseous products of combustion to passoutward and around and through the headers of the manifolds, thusreaching all sides of the tubes freely.

The operation will be readily understood. The tube manifolds beingexposed to the greatest heat, the circulation of water therein willnaturally be upward. While the outer shell of the jacket is exposed toradiation of heat and is therefore coolest, the sheet of wa terimmediately adjacent thereto will circulate downward.

The construction and form of the tube; manifolds, as will be seen, adaptthem to their consecutive positions and relations within the cylindricalshell, leaving substantially parallel spa-ces between, while the centralopenings through the manifolds allow the heated gases to pass freelythrough and between the sets of tubes of each manifold, as betweenadjacent manifolds.

I claim as my invention and desire to secure by Letters Patent of theUnited Statesl. A water-heater consisting of a waterjacketed shellcombined with a plurality of radially-arranged manifolds, eachconsisting of upper and lower headers of substantially segmental formwith central perforations, united by tubes arranged around saidperforations, and each header having a connection with the water-spacein the jacket, substantially as described.

2. A water-heater consisting of a waterjaoketed shell, combined with aplurality of radially-arranged manifolds each consisting Ioo of an upperand a lower header united by tubes, atubular connection leading fromeach header into the water-space of the jacket, and a deieotor-platedisposed centrally within the heater above the upper set of headers andoverlapping the inner edges thereof, substantially as described.

3. In a water-heater of the character indi-L cated, the combination,with the water-jacketed shell, of manifolds arranged in concentrioseries connected with the water-space of said jacket, and othermanifolds arranged in the same concentric series with branches extendedindependently outward, without connection with said water-jacket,substantially as set forth.

4. A water-heater consisting of a cylin-
